Most Common Reasons an LG Refrigerator Stops Making Ice

Here is a detailed breakdown of each cause and what to do about it.

Ice Maker Accidentally Turned Off

The on/off switch is the first thing to check when your LG refrigerator is not making ice. On top-freezer and side-by-side models, the switch is typically a lever or wire arm that you lift to turn off and lower to turn on. On French door and bottom freezer models, it is often a button on the ice maker unit itself or accessible through the control panel. Switch the ice maker on and wait a few hours to confirm production has resumed.

Jammed or Overfilled Ice Bucket

Ice can build up around the bucket, knock it out of alignment, or block the dispenser chute. Remove the ice bucket, inspect it for ice clumps or buildup, thaw any frozen sections, and reinstall it correctly. The bucket must click firmly into its housing for the ice maker to operate.

Low Water Pressure Below 20 PSI

According to Angi, an ice maker generally needs at least 20 PSI of water pressure to work properly. Below that threshold, water flow to the ice mold becomes restricted and ice production slows or stops entirely. You can test your household water pressure with an inexpensive gauge attached to any faucet.

Frozen or Kinked Water Supply Line

The water supply line runs from the shut-off valve behind the refrigerator to the ice maker. A frozen section blocks water entirely, while a kinked line restricts flow. Pull the refrigerator away from the wall, inspect the line for kinks, and feel along it for hard or frozen sections. Thaw a frozen line using a hair dryer set to low heat, keeping it moving to avoid damaging the line.

Clogged or Expired Water Filter

The water filter supplies water to both the dispenser and the ice maker. According to LG’s official guidance, corroborated by LGParts.com, the filter should be replaced every 6 months. In hard water areas, Angi recommends replacing it twice a year. A clogged filter reduces flow to the ice mold and can cause slow production or complete failure. See the refrigerator cleaning and maintenance guide for full filter replacement instructions and general upkeep tips.

Freezer Temperature Too Warm

According to LG’s official troubleshooting guidance, the ice maker shuts off production when the freezer reaches 10 degrees F or warmer. The optimal freezer temperature for ice production is between -4 and 0 degrees F. A freezer running at 20 to 30 degrees F will stop making ice entirely. Check the temperature setting on the control panel and give the freezer 4 to 6 hours to stabilize after any adjustment. For related issues, see this resource on common freezer problems.

Faulty Water Inlet Valve

The water inlet valve is a solenoid-operated valve that opens to allow water into the ice maker. If the ice-maker-specific port on the valve fails, water will still reach the dispenser but not the ice mold. This is the most common hardware explanation for why water works but ice does not form. Replacing a water inlet valve requires disconnecting the appliance from power and the water supply; a certified technician should handle this repair if you are not experienced with appliance disassembly.

Blocked Ice Maker Sensor or Arm

Most LG ice makers use a sensor-driven system, as noted by LGParts.com. If the sensor arm or optical sensor is blocked by ice buildup or a misplaced item in the freezer, the system reads the bin as full and halts production. Clear any obstructions around the sensor arm and confirm nothing in the freezer is pressing against it.

Defective Auger Motor

The auger motor moves ice from the storage bin through the dispenser chute. A defective motor will prevent ice from dispensing even when the ice maker is producing normally. This issue typically requires professional repair or a full motor replacement.

 

 

LG Refrigerator Not Making Ice But Water Works

When an LG refrigerator is not making ice but water works from the dispenser, the problem is isolated to the ice-making circuit rather than the main water supply. The most likely causes, in order of likelihood, are:

1. Faulty water inlet valve, specifically the ice-maker port
2. Frozen fill tube between the water supply line and the ice mold
3. Failed ice mold thermostat preventing the mold from reaching freezing temperature
4. Broken ice maker assembly requiring full replacement

The water inlet valve is the most common culprit. Confirming this diagnosis before calling a technician can save time and money, since a multimeter test of the valve takes minutes. Homeowners with other brands experiencing the same symptom can refer to this guide on ice maker not making ice but water works for additional diagnostic context.

How to Reset Your LG Ice Maker (Step-by-Step)

Resetting the ice maker clears electronic glitches and forces the unit through its production cycle. This resolves the majority of software-related failures.

 

How to Reset a Standard LG Ice Maker

1. Open the freezer and remove the ice bucket.
2. Locate the test and reset button on the front face or underside of the ice maker module.
3. Press and hold the button for 3 to 5 seconds until the ice maker begins its test cycle.
4. Replace the ice bucket when the cycle completes.
5. Wait 24 hours for the first new batch of ice.

Note: If the test cycle runs but ice production still fails after 24 hours, the issue is likely hardware rather than software, per LGParts.com guidance.

How to Reset an LG Craft Ice Maker

1. Open one refrigerator door fully.
2. Press and hold the Refrigerator button on the control panel for 3 seconds to confirm the unit is not in demo mode.
3. If the Craft Ice maker remains unresponsive, unplug the refrigerator from the wall outlet.
4. Leave it unplugged for 10 minutes.
5. Plug the unit back in and allow 24 hours for Craft Ice production to resume.

Note: LG introduced Craft Ice in 2019 as a feature that produces slow-melting round ice spheres. The Craft Ice maker is a separate system from the standard cube maker. Both must function independently.

How to Reset an LG ThinQ Ice Maker

1. Open the LG ThinQ app on your smartphone.
2. Select your refrigerator from the registered devices list.
3. Go to the Smart Diagnosis feature.
4. Follow the in-app prompts, which will guide you through the diagnostic and reset process.
5. If the app identifies a fault code, note the code and contact LG support directly through the app for model-specific resolution

New LG refrigerators require 24 to 48 hours after installation before producing the first batch of ice, according to LG’s official support documentation. If your LG refrigerator is not making ice within that window, allow the full 48 hours before concluding there is a problem.

LG Ice Maker Not Making Ice by Model Type

LG produces several refrigerator configurations, and each has a distinct ice maker system with different locations, access points, and reset procedures. Use the section below that matches your model.

LG French Door Refrigerator Ice Maker Not Working

French door LG refrigerators typically house the ice maker inside the refrigerator section in the upper left, not in the freezer. This is the SpacePlus or Slim SpacePlus Ice System configuration. Because the ice maker sits in the fresh food compartment, door seal integrity is especially important. A worn gasket on a French door model allows warm air in and can stop ice production entirely. Check the door gasket and clean it with warm soapy water if it looks dirty or misshapen.

LG Bottom Freezer Ice Maker Not Working

Bottom freezer LG refrigerators place the ice maker inside the freezer drawer at the bottom of the unit. Accessing the test button requires opening the freezer drawer and locating the ice maker module at the back. If you have an LG fridge not making ice in a bottom freezer configuration, check for ice buildup around the fill tube and the back wall of the freezer drawer, as these models are particularly prone to fill tube freezing due to their lower position. For a broader look at the same brand, see common LG refrigerator problems and fixes.

LG Side by Side Refrigerator Ice Maker Not Working

On LG side by side refrigerator ice maker not working situations, the ice maker is located in the upper left section of the freezer compartment. The dispenser is built into the door, which means a door switch failure can stop both ice and water dispensing at the same time. If neither ice nor water comes out of the door but the ice maker appears to be running, check the door switch first before assuming an ice maker component has failed.

LG ThinQ Refrigerator Ice Maker Not Working

If your LG ThinQ refrigerator is not making ice, open the app and run Smart Diagnosis before any manual troubleshooting. The app can identify error codes that pinpoint whether the failure is in the water supply, temperature regulation, or ice maker assembly itself. The EID error code on LG refrigerator display panels typically indicates a freezer compartment ice maker sensor failure, per Beaconsaves.com repair guidance. Use the app to capture the code before contacting LG support.

LG Craft Ice Not Working

LG introduced Craft Ice in 2019 as a premium feature available on select French door and side-by-side models. A Craft Ice-equipped refrigerator produces three ice types: Craft Ice spheres, standard cubes, and crushed ice. The Craft Ice maker operates as a separate system and produces approximately 3 ice spheres per day. Common Craft Ice issues include the sphere mold freezing up, jamming inside the mold, or the unit entering a fault state after a power interruption. It is worth noting that some customers have reported Craft Ice failures within the first year of purchase, which has been the subject of class action complaints per Milberg Law reporting. The recommended first step for most Craft Ice failures is the 10-minute unplug reset described above. If the unit fails repeatedly, contact LG support and reference your warranty status before paying for a repair.

LG Ice Maker Not Dumping Ice

"Not dumping ice" is a different problem from "not producing ice." If the ice maker is running and filling with water but ice is not dispensing into your glass, the issue is in the dispensing system rather than the production system.

Common causes of ice not dispensing:

• Ice bucket is misaligned or not seated correctly in the housing
• Ice has clumped or bridged inside the bucket, forming a solid mass that blocks the auger
• The auger motor is jammed or has failed
• The dispenser flap on the door is frozen shut or the motor that operates it has failed
• The ice maker is sending ice to a full bucket, triggering the shutoff sensor

Remove the ice bucket, break up any clumped ice, reinstall it firmly, and press the dispenser lever. If ice flows normally after this, clumping was the cause. Clumping usually results from the freezer being opened frequently or the temperature being set slightly too warm.

How to Troubleshoot Your LG Ice Maker Step by Step

Work through this checklist in order before calling a technician.

Safety Note: Before inspecting internal components or moving the refrigerator, disconnect it from the power outlet. Water supply lines carry live water pressure. If you are not comfortable with any step, contact a licensed appliance technician.

1. Check the ice maker on/off switch. Confirm it is in the ON position. Switch location varies by model (see the model-specific section above).
2. Verify the freezer temperature. It must be at -4 degrees F (-20 degrees C) or colder. According to LG’s official troubleshooting guidance, the ice maker shuts off production at 10 degrees F or warmer.
3. Confirm water pressure at or above 20 PSI. Use a pressure gauge at any household faucet.
4. Check the water supply shut-off valve behind the refrigerator. It must be fully open.
5. Inspect the water filter. If it is older than 6 months, replace it with a genuine LG filter.
6. Examine the water supply line for kinks or frozen sections. Straighten kinks and thaw frozen sections with a hair dryer on low.
7. Remove the ice bucket and inspect for jams, clumps, or misalignment. Thaw if needed and reinstall.
8. Check door gaskets and seals for gaps or damage. Close the door on a piece of paper; it should grip with light resistance.
9. Run the test and reset cycle. Follow the reset steps in the section above for your specific model.
10.  Use LG Smart Diagnosis if your model supports ThinQ. Open the app and run a scan before escalating to a service call.
11. Check the display panel for error codes. Note any codes displayed and look them up in your model’s user manual or contact LG support.

To find your LG refrigerator model number, check the sticker inside the left door jamb. Having the model number ready before contacting LG support or a technician will speed up diagnosis.

Under ideal conditions, a standard LG refrigerator produces approximately 100 ice cubes per 24-hour period, according to LG’s official support documentation. The Craft Ice maker produces approximately 3 ice spheres per day. If your unit is producing ice but at a lower rate than expected, check the freezer temperature and water pressure before concluding there is a malfunction.
